STONE-2270 Digital Music Production System

The header runs across the top of the machine. Use it to switch the center screen, set the tempo and control playback.

• Sampler · Sequencer · Mixer · Sounds · Project
  These five tabs change what the center screen shows. Each one is explained in section 3.
• BPM
  The tempo, from 50 to 220 beats per minute. Type a number, or use − and + to move it one beat at a time.
• Tap
  Tap this button in time with a song, three times or more, and the machine sets the tempo to match.
• Back to Start (⏮)
  Jumps back to bar 1 and keeps playing, so you can hear your beat from the top or start a new pass. When stopped, it plays from the start. Shortcut Home.
• Record (red dot)
  Starts recording on the armed track. If the beat is stopped, it starts playing too. Shortcut T.
• Play (green arrow)
  Plays your beat on a loop. Press again to stop. Shortcut Space.
• Stop (white square)
  Stops playback and recording.
• Settings (gear)
  Opens the theme color wheel, MIDI controller setup, Low CPU mode, Full Screen and the keyboard shortcut list. See Settings & MIDI.

Hit a pad with your mouse, a touch screen, your computer keyboard or a MIDI controller. The pad you hit last is the selected pad (white outline), and the Sampler edits that pad.

• Bank A · B · C · D
  Four sets of 16 pads. Bank A starts with STONE Classic, Bank B with STONE Trap. Banks C and D hold your own sounds and chops.
• Kit
  Loads a full drum kit onto the bank you are on. Pick a bank first, then a kit.
• Note Rpt
  Note repeat. While the beat plays, hold a pad and it repeats on the Quantize grid. Great for hi-hat rolls.
• One Shot / Gate
  One Shot plays the whole sound. Gate plays only while you hold the pad. This is set per pad.
• Load Sound
  Opens the Sounds browser, where you can listen to every sound and drag the one you want onto any pad. Right-click a pad to open the full library with a pad picker instead.
• Keyboard
  Pads 1–16 are 1234 · QWER · ASDF · ZXCV, starting top left. Hold Shift to hit softer.

Drum kits included

The Sampler brings new sounds into the machine, then lets you cut and shape them. New sounds always load onto the selected pad (the one with the white outline), so pick your pad first. Use Bank C or D if you want to keep your drum kits on A and B.

Get a sound

• Upload
  Load an audio file from your computer (WAV, MP3, OGG, M4A, FLAC or AIFF). Long files keep the first 5 minutes.
• Drag & drop from your computer
  Drag sound files straight from your desktop or a folder onto the machine. Drop them on a pad to load it (drop several files and they fill the next pads in order), on the turntable to scratch, on the Sampler for the selected pad, or on a track to add them to your song (see Tracks). Dropping a .stone file opens that project. A dashed outline shows where the file will land.
• Link
  Paste a direct link to an audio file. Some websites block this. If so, download the file and use Upload.
• Mic
  Opens the microphone recorder. Pick your microphone from the Input list (built-in, USB mic or audio interface), watch the level meter, then use ● Record, ■ Stop and ▶ Play Take to hear it back. Happy with it? Press Load to Pad. Takes can be up to 60 seconds, and silence at the start and end is trimmed for you. Use headphones to stop feedback.
• Tab Audio
  Sample live from another browser tab, such as a YouTube video. Works in Chrome and Edge on a computer. Pick the tab and tick Share tab audio, play the video, then press Stop & Load.
• Samples
  Opens the sound library: Drum Kit Sounds (every sound from every kit), Scratches, SP1200 Drums and Dr. Dre Samples. Choose the bank and pad under Load Onto, search or filter by type, press ▶ to preview, Pad to load it on that pad, or Deck to put it on the turntable.

Edit the sound

• Waveform
  Drag the two white markers to set where the sound starts and ends. The pad plays when you let go so you can hear it.
• Chop 16
  Cuts the selected part into 16 equal slices and puts them on Bank D, one per pad. Perfect for chopping a loop.
• Trim
  Keeps only the part between the markers and throws away the rest.
• Reverse · Normalize
  Reverse plays the sound backward. Normalize makes it as loud as it can go without clipping.
• To Deck
  Puts the selected pad's sound on the scratch turntable.
• Warp (time stretch)
  Changes a sound's tempo without changing its pitch, so a loop or vocal fits your beat. Press WARP, enter the sound's Original BPM (or press DETECT, or type its length in bars) and the Target BPM, then press WARP. ÷2 and ×2 fix a guess that is half or double speed. Tick Follow the song tempo and the sound re-warps by itself whenever you change the BPM. UNDO WARP brings back the original.
• ▶ Play (green arrow)
  Plays the sound on the selected pad so you can hear your trim and edits.
• ■ Stop (square)
  Stops every sound that is playing right away: long samples, held notes, previews and the turntable. Shortcut Esc.
• Remove (trash can)
  Takes the sound off the selected pad so the pad is empty again. Any hits for that pad in your song are removed too, and you are asked to confirm first.
• Sample Edit knobs
  Start, End, Fade In, Fade Out, Level and Pitch (up to 24 semitones up or down).

Effects

The effects work on the whole mix. Pick an effect, press On, then turn its knobs. Turning a knob switches its effect on.

Browse every drum kit and sample, listen to each sound, then grab it and drop it right onto a pad.

1. Open the Sounds tab at the top of the machine (or press Load Sound under the pads).
2. Pick a library (Drum Kit Sounds, Scratches, SP1200 Drums or Dr. Dre Samples). For drum kits, choose a kit to see its 16 sounds.
3. Click any sound to hear it. Use Search or the type filter (Kick, Snare, Hi-Hat…) to narrow the list.
4. Drag the sound onto any pad on the left. The pad gets a white dashed outline when you are over it. Let go and the sound is loaded and plays once.
5. Drop a sound onto the turntable instead to scratch it.

The step sequencer shows the 16 pads of the current bank as rows and 16 steps per bar as columns. It opens to a 4-bar loop. Click a step to add a hit on the armed track, and click it again to remove it.

• Drag a hit
  Grab any lit step with the mouse and drag it to a new step or another row. Let go and it moves there, and you hear it.
• Drag a pad in
  Drag a pad from the left onto any step to place that sound right there.
• Fix Timing
  One click straightens out your whole song. Every hit and note snaps exactly onto the Quant grid (1/16 if Quant is off), so loose timing lines up perfectly. Want it tighter? Pick a bigger grid like 1/8 or 1/4 and press it again. Undo puts it back.
• Bars
  How long your song is, from 1 up to 128 bars. Use − and +, press +4 to add four bars at a time, or type a number. New bars start empty (use Duplicate in the Song Editor to copy a section into them). Making the song shorter asks first before removing anything past the new end.
• Quant
  Quantize snaps recorded pad hits to a grid, from 1/4 down to 1/64, with triplet options. Choose Off for no snapping.
• ◀ Bar ▶
  The grid shows one bar at a time. Use the arrows to move between bars. With Follow on, the grid jumps along with the playhead while the beat plays.
• Swing
  Pushes every other 16th note late for a looser, human groove. 0 is straight, 60% is heavy swing.
• Metro · Count-In
  Metro plays a click. Count-In gives you one bar of clicks before recording starts.
• Undo · Redo
  Steps back or forward through your changes. Shortcuts Ctrl+Z and Ctrl+Y.
• Clear Track · Del Song
  Clear Track erases the armed track. Del Song erases everything so you can start over. Undo brings it back.
• Editor
  Opens the big Song Editor where you can move, copy and delete any part of your song. See Song Editor.
• Step RPT (rolls)
  For hi-hat rolls and fast fills. Pick a rate: 1/32 (2 hits per step), 1/32T (3 hits per step, triplet), 1/16T (triplet 16ths) or 1/64 (4 hits per step). Now click a step to place a roll, or drag across steps to paint rolls. Click a roll again to remove it. Rolls show striped. Set it back to OFF for single hits.
• Mixer ⧉
  Opens the Mixer in its own window so you can mix while you program. See Mixer.

One channel strip for every track. With more than 8 tracks, scroll the strips sideways. Press + TRACK to add another one.

• Fader
  The track's volume. Slide it up or down.
• Pan
  Moves the track left or right in the stereo field.
• Rev · Dly
  How much of the track goes to the reverb and the delay.
• M · S
  Mute silences the track. Solo plays only the soloed tracks.
• Bend · Range
  Chooses what the Bend lever controls (7 Keys, Scratch Deck or Both) and how far it bends, from ±1 to ±12 semitones.
• Pop Out ⧉ (mixer window)
  Press POP OUT here, MIXER ⧉ in the Sequencer or MIXER in the Song Editor to open the Mixer in its own window. It stays open while you use the Sequencer, Sampler or Song Editor. Drag its top bar to move it and drag the bottom-right corner to make it bigger or smaller. Press DOCK (or the Mixer tab) to put it back.

• Name · Save
  Name your beat and press Save. Saved beats are listed below with Open and Delete.
• New · Demo
  New starts a blank beat. Demo loads a ready-made beat to play with.
• Play Loop
  How many times your loop repeats in the download: 1, 2, 4, 8 or 16 times.
• Format
  MP3 at 320, 256 or 192 kbps, or WAV in 16-bit or 24-bit for full quality.
• Download
  Renders every track, effect, bend and scratch into one stereo file and downloads it. Your beat's name becomes the file name and the MP3 title.
• Stems
  Saves every track that has something on it as its own file, all packed in one .zip. Every stem is the same length and starts at the same moment, so they line up perfectly when you drop them into a studio program or send them to a mixing engineer. Pick Stems as: WAV 24-bit (best for studios), WAV 16-bit, or the same as the Format above.
• Export .STONE · Import .STONE
  Saves your whole project, including your own samples, as one file. Import it on another computer to keep working.

Shows every track and every hit and note in your loop. A white line moves across while the beat plays. A new song starts with 8 tracks (Track 1 to Track 8), and you can add as many as you want. When there are more than 8, the list scrolls.

• R (Arm)
  The armed track (lit red) is where new recordings go. Click R or a track name to arm it.
• ✎ Name & Color
  Click the pencil next to a track, double-click its name, or click the track name button at the top left of the Sequencer. A big Track Name & Color window opens. Pick any track with the numbered buttons, type a new name (up to 16 letters), tap a color (or the rainbow circle for any custom color), then press SAVE or Enter. In the Song Editor, use the RENAME button or double-click a track name. Names and colors are saved with your project, and names are used for stem file names.
• M · S
  Mute and Solo, the same as in the Mixer.
• + TRACK · − TRACK
  + TRACK adds a new track and arms it. There is no limit. − TRACK deletes the armed track and everything on it (Undo brings it back). You'll also find + TRACK in the Mixer and the Song Editor.
• Edit Song
  Click Edit Song, or click anywhere on the track view, to open the Song Editor.
• Audio & MIDI on any track
  Every track can hold audio files and MIDI. Drag a WAV, MP3 or other sound file from your computer onto a track name, the track view or the Song Editor, or press + FILE to pick files for the armed track. Audio becomes a clip on the timeline (the song gets longer if it needs to). A MIDI file opens a short window: play it on the synth (pick a sound) or on the drum pads (notes 36 to 51 play pads 1 to 16), and optionally switch the song to the MIDI file's tempo. In the Song Editor, drag a clip to move it and double-click it to change its level, warp it to the song tempo, or delete it.

The Song Editor opens over the machine and shows every track, bar and hit full size. Each colored block is one piece: a drum hit, a key note, a bend or a scratch move.

• Select
  Click a piece to select it (it turns white and you hear it). Shift-click to add more, or drag a box on empty space to grab a group.
• Move
  Drag selected pieces left or right to move them in time, or up and down onto another track. Hold Alt while dragging for no snap.
• Snap
  Sets the grid pieces snap to while moving: 1 beat, 1/8, 1/16, 1/32 or Off.
• Fix Timing
  Highlight pieces (drag a box or Select All), then press FIX TIMING to snap them exactly onto the Grid. With nothing selected it fixes the whole song.
• Grid
  Top right of the editor. Sets the grid for dragging and Fix Timing (1/4 to 1/64, triplets too). Changing it while pieces are highlighted snaps them to the new grid right away. Hold Alt while dragging to move a piece freely.
• Duplicate
  Copies the selected pieces and places the copy right after them. Shortcut Ctrl+D.
• Delete
  Removes the selected pieces. Shortcut Delete or Backspace.
• All
  Selects every piece in the song. Shortcut Ctrl+A.
• Clear Track

• Delete Song
  Erases the whole song so you can start over. You are asked to confirm first.
• Undo · Redo · Play · Close
  Every change can be undone. Press Play to hear your edits while you work, and Close (or Esc) to go back to the machine.

Put any sound on the record and scratch it for real. The sound follows your hand forward and backward at the speed you move.

• The record
  Click and drag in a circle to scratch. Hold still to stop the sound. Let go and the record returns to its normal speed.
• Start / Stop
  Spins the record up like a motor, or winds it down to a stop. Shortcut B.
• Reverse
  Plays the record backward.
• Cut
  Hold to silence the deck, like a crossfader. Tap it while scratching for cuts and transforms. Shortcut N.
• Load Pad
  Puts the selected pad's sound, with its trim, on the record.
• Samples
  Opens the library so you can put a scratch loop, drum or sample on the record.
• Pitch
  Speeds the record up or down. Choose a range of ±8%, ±16% or ±50%, and press Reset to go back to normal.
• Track
  The menu above START, beside the turntable. Picks which track the turntable plays and records on. It starts on Scratch, so your scratches always get their own channel in the Mixer and their own file when you export Stems, no matter which track is armed. Switch it to any track and the scratches you already recorded move with it.

Push the lever up to bend the pitch up, or pull it down to bend it down. Let go and it springs back to the center. The amount shows under the lever in semitones.

• Keyboard
  Hold ↑ or ↓ to bend all the way. Let go to spring back.
• Target & range
  Choose 7 Keys, Scratch Deck or Both, and the bend range, in the Mixer tab.

Seven big keys play the seven notes of a scale, so every note fits. The note name shows on each key. You can play several keys at once for chords.

• Instrument
  Lead, Bass, E-Piano, Pad, Pluck, Organ or Brass.
• Scale
  Major, Minor, Pentatonic, Minor Pent, Blues, Dorian or Chromatic.
• Root note
  The key your scale starts on, C through B.
• Oct − / +
  Moves all seven keys down or up one octave.
• Sustain
  Notes keep ringing after you let go. Turn Sustain off to release them.
• To Track
  Chooses which track your key notes record onto. This is the same as arming a track.
• Keyboard
  Keys 1–7 are GHJKL;'.

The big Master knob sets the overall volume of everything. The red M in the top right corner mutes everything at once. Click it again to bring the sound back. Mute only affects what you hear, never your exports. The L and R meters show the level of your mix: green is healthy, yellow is loud and red is the top. A built-in limiter keeps your downloads from clipping.

1. Set your BPM, and in the Sequencer tab choose how many Bars and the Quant setting (1/16 is a good start).
2. Arm Track 1 with its R button and pick a kit.
3. Press Record (T). With Count-In on, you hear one bar of clicks and see a big 4 · 3 · 2 · 1 countdown over the pads. Start playing when it shows REC. Hits made during the countdown are not recorded, except a hit right before the 1, which lands on the 1.
4. Play your drums on the pads. The loop keeps going, so you can add more on each pass. This is called overdubbing.
5. Press Stop. Fix any hits in the step sequencer, or press Undo.
6. Arm Bass, set the 7 Keys instrument to Bass, and record a bass line the same way. Then do keys, scratches and samples on their own tracks.
7. Mix it in the Mixer, add effects, then Save and Download your MP3 in the Project tab.
